Clowns staring into alternate universes

The eyes of a clown were made to stare. They often do not enjoy the things they see. They see your hatred, pain, anger, and sadness while all they wanted was to bring happiness to the world. Now that the human race has taught them the ways of anger and that their laughter has no place, they will adapt. Humans have taught them what it means to murder, so they have trained the clowns to be the downfall of the human race without even realizing they did.
